Spring is a good time for chicken farmers to fill in cages. However, if the relationship between cold preservation, warmth and ventilation in the chicken coop can not be dealt with, it often leads to lack of oxygen in chicken houses, which seriously affects the normal growth of chickens, thereby reducing the economic benefits of raising chickens. To prevent the lack of oxygen in the brooding room, so as not to affect the growth of the chicks and threaten the life safety of the chicks, the following measures can be taken:
Strengthen ventilation in breeding houses
The chicken's body temperature is high, and the breathing gas is more than 2 times higher than mammals. It needs more oxygen. As long as the ventilation in the chicken house is constantly enhanced to ensure that there is enough fresh air outside, the chicken can be lively and healthy and less sick. The house is usually ventilated once every 2 to 3 hours. Each ventilation is between 20 minutes and 30 minutes. Before ventilating, the temperature of the house should be increased. When ventilating, care should be taken that the wind cannot be blown directly to the chicken body to prevent the onset of chicken cold.
Reduce feeding density
Broilers are generally raised in large numbers, with high numbers and high density, and lack of oxygen in the air. Especially in high temperature brooding and high temperatures in chickens, long-term lack of fresh air often results in debilitating chicks, increased mortality in chickens, and increased chances of transmitting diseases through the air, especially when oxygen levels are low, often causing respiratory illnesses. . Therefore, to reduce the rearing density, it is possible to raise 9 broilers of about 1.5 kg per square metre. If broilers are raised on the Internet, the density can be doubled.
Pay attention to heat preservation method
Some farms only emphasize thermal insulation and do not pay attention to ventilation, resulting in a severe lack of oxygen in the houses and frequent carbon dioxide poisoning. When the coal stove is used for heat preservation, the stove sometimes smokes or smokes. It is prone to gas poisoning. Even normal heating can compete with the chicken for oxygen. It is best to place the stove outside the shed, which can effectively prevent harmful gas poisoning.
Choose suitable heat source
In order to prevent certain heat sources from competing with the chicks for oxygen, and to avoid the release of harmful gases and fumes when certain heat sources generate heat during the combustion, the direct burning of fuels such as firewood, coal, charcoal, and hibiscus should be avoided during brooding and heating. , but should use the power, or the use of ramp insulation form of heat insulation.
Timely replacement of litter and excrement
The litter and excrement will ferment at a certain humidity and temperature, consuming some of the oxygen in the brooding chamber, and will emit gases that are harmful to the growth and safety of the chick. In order to prevent and reduce the occurrence of this phenomenon, the timely replacement of litter and excrement is a way to reduce and prevent brood chamber hypoxia. In the removal of litter and excrement, care must be taken not to uncover all the coverings used for thermal insulation. Instead, choose a time when the weather is good and the temperature is high, and quickly add new litter.
Prevent stress
Chickens are sensitive to nerves. The sudden appearance of any new sounds, colors, animals, and objects can cause adverse stress reactions in chickens, consume a lot of physical energy, increase oxygen consumption, and are more harmful to growth and weight gain. . Therefore, it is necessary to maintain normal and orderly living patterns of broilers and keep the chickens quiet and stable. At the same time, it is necessary to keep the sheds sterilized and cleaned regularly.
Spraying oxygenated drugs
Peracetic acid is a broad-spectrum and highly efficient chemical disinfectant drug that is unstable in nature but can release oxygen and acetic acid. According to this characteristic, spraying peracetic acid in a chicken house at a proper time can increase oxygen and secondly it can be used for chickens. House disinfection, the third to neutralize some of the harmful alkaline gas.
A Heating Pad is a pad used for warming of parts of the body in order to manage pain. Localized application of heat causes the blood vessels in that area to dilate, enhancing perfusion to the targeted tissue.
Heating pad is used for soothing painful joints & sore muscles & promote blood circulation in the form of heat therapy. Normally it is regulated by a controller with 3-4 heat settings.
